IMPROVEMENT lN APPARATUS FOR MANUFACTURE OF LAMP-BLACK.

Specification forming part of Letters Patent No. 162,492, dated April27, 1875; application filed March 6, 1875.

To all whom it may concern:

Be it known that I, PETER NEEF, of Gambier, in the county of Knox andState of Ohio, have invented certain new and useful Improvements inMachinery for the Manufacture of Lamp-Black; and I do hereby declare thefollowing to be a full, clear, and exact description .of the invention,such as will enable others skilled in the art to which itpertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in apparatus for manufacture oflamp-black from carbureted oils and gases; and consists in hunt in g thesaid oil or gas in an apartment conveying the products of combustionthrough pipes or flues that pass through a tank containing water.

In the drawings, Fig. 1 is a sectional view of an apparatus embodying myinvention. A is an apartment for burning oil, gas, or matter from whichlamp-black is to be made.

The process of burning the said oil or gas, the burners by which theyare burned, the particular construction of the burning-chamher, and thearrangement of its interior, form no part of this invention.

B is a flue leading from the burning-chamber A, whereby the products ofcombustion are led into pipes or flues O. D is a tank or apartmentcontaining water, and through which the said tubes or flues 0 pass.

The lamp-black is partially deposited in the burning-chamber A and lineB; but it is designed that the flues 0 shall, in the most part, collectthe said lamp-black. The apartment A and the flue B may be slightlyremoved from the tank or chamber D, so as to avoid any danger from fire.The apartment A and fines B and G are all so constructed that they maybe readily scraped or brushed on all those surfaces where lamp-black maycollect. For this purpose a cap or door, E, may be provided, by openingwhich the dues C may be readily cleaned, and a suitable door or doors,F, admit of ready communication with the burning-chamber A, wherebyaccess can be had to the burners and other apparatus contained in thechamber. The water contained in the tank D will soon become heated bythe products of combustion passing through the fiues C. To avoid thisthe water may be supplied to the tank D from a higher reservoir, wherebyit may be continually fed in and permitted to escape, thus maintainingthe water in a cool state.

The carbonaceous matter is burned in a suitable chamber, and in orderthat the products may be rapidly cooled and not permitted to escape inlarge quantities at the distant end of the flues, it is necessary todivide up the volumes of the products of combustion so thatit may passthrough a numberot' flues, and thus be rapidly cooled. If the saidproducts were made to pass through a single fine, the flue would have tobe so large as not properly to effect the cooling of the products,while, if it were made small, the draft would be so great that thecooling could not be properly effected. It, is, therefore, importantthat there should be several of the said flues, so that the productsbeing divided up and passed through these several flues will becomerapidly cooled, so that the lamp-black will be nearly, if not all,deposited in the said fines, and not be wasted in a great degree bybeing carried out at the other end of the fines.

What I claim as new is The apparatus for manufacture of lampblack,consisting of the combination, with a suitable burning-chamber, A, of awater-tank having two or more flues, O, communicating with saidburning-chamber, whereby the products of combustion may be divided up,substantially as and for the purpose described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER NEFF.
